According to Vulture, the studio is currently in final negotiations with De Niro to star opposite Douglas in a script by Dan Fogelman (Crazy, Stupid, Love). The twosome would play oldsters who both fall for the same "girl." The film is described as The Hangover for golden agers -- four men of a certain age head out to Vegas for a bachelor party.

Jon Turteltaub (National Treasure) is set to direct the film. The next step is getting Christopher Walken on board, but not before finalizing a deal with De Niro.
